The painting of this shell is very characteristic, and the 
outer surface of it is further distinguished by its smooth 
porcelain appearance. It is an extremely rare species ; 
the specimen represented in the ‘ Conchologia Systema- 
tica ’ is in Mr. Cuming’s collection, and that here figured 
from the British Museum was formerly in the Tankerville 
collection, afterwards in that of W. J. Broderip, Esq.

fusiformly oblong, whorls seven in number, granosely 
striated round the upper part, smooth round the

. chestnut.

All Mr. Cuming’s examples of this species are distin- 
guished by the same broken interrupted style of painting 
with which this is characterized. 
Species 38. (Mus. Cuming.) 
Achatina columna. Achat, testd elongato-turritd, an- 
fractibus septem, subrude granoso-striatis, suturis de- 
presso-concavis, columella contortd, callosa, plicato- 
producta, aperturd pared ; flavidd, castaneo undique 
fulguratd, columella et apertures fauce ccerulescente- 
albist

striated, sutures depressly concave, columella twisted, 
callous, produced in the form of a plait, aperture

It is somewhat remarkable that no species has been dis- 
covered to approximate to this. Lamarck, believing it to 
be an inhabitant of freshwater, placed it originally in the 
genus Lymnesa.
